%X The radiative opacities of iron and bromine plasmas have been calculated using an average atom (AA) model with modification of the transition energy. The line positions obtained after the modification have better agreement with the results of the detailed term accounting model. However,discrepencies still exist for some strong transition peaks. To eliminate the discrepencies the charge state distribution should be included. The mean opacity of iron was calculated. We found that the transition energy shift has obvious effect on the mean opacity of iron plasma at relatively lower densities.
